Abstract

一种用于管道因热胀冷缩而引起位移的密封式 管道伸缩器,它主要由外套管、伸缩管、弹簧推进器、 活动圈、固定圈及调节螺栓构成。在弹簧推进器及自 身介质的压力作用下,使管道始终处于密封状态,在 频繁伸缩的过程中,可避免泄漏。并且,它的体积小, 重量轻。制造工艺简单,易装配,检修方便,造价低, 又容易保温。

Description

本实用新型属于补偿管道因热胀冷缩而引起位移的一种伸缩补偿器,它适用于输水、输油、输气等各种管道。
目前,有一种管道由于热胀冷缩而发生位移的弹性套管补偿器,它主要由伸缩管、外套管、法兰、弹簧及密封件构成。该补偿器是利用弹簧的弹力压紧密封件,克服了老式伸缩节因伸缩管频繁伸缩所造成密封件松驰,易泄漏的缺点。但是,由于弹簧长期在高温、高压下工作会逐渐失去弹性,使密封件松驰而产生泄漏。并且在伸缩管的外径装有多个弹簧,因此,组装困难,不便检修。同时其体积大,造价高。
本实用新型的目的是在于提供一种密封式管道伸缩器,它可以同时利用弹簧推进器及自身介质的压力,将密封件压紧,密封。
其具体解决方案是:将伸缩管带有导向块的一端装入外套管的内腔,使该外套管的内腔臂与伸缩管外臂之间形成一环形空腔。在该环形空腔内依次装有活动圈、密封件、弹簧推进器及固定圈。可利用调节螺栓通过均布在固定圈的螺孔将弹簧推进器压紧,使其对密封件产生一压力,又利用充满压力室的管道内自身介质,以相反的方向给密封件一压力,上述两种压力同时将密封件压紧,从而进行密封。
再则,弹簧推进器是由弹簧及带有弹簧座的上、下压板用螺钉柔性连接成一整体的。
本实用新型的具体实施例结合附图加以说明:
图1为伸缩器的主视图。
图2为伸缩器的A-A剖视图。
在图1与图2中,外套管(12)的一端通过封闭圈(13)与连接管(14)焊接。其另一端面装有封盖(2),使外套管(12)呈封闭状态,并在此端将伸缩管(1)带有导向块(11)的一端装入其内腔,使外套管的内腔臂与伸缩管的外臂之间形成一个环形空腔。在该空腔内依次装有与其滑动配合的活动圈(9),用石棉、橡胶石棉、橡胶等材料制成的密封件(8),弹簧推进器及用螺钉(15)紧固于外套管(12)上的固定圈(4)。而弹簧推进器由上压板(5)、下压板(7)及多个弹簧(6)用螺钉柔性连接成一体,并与外套管内腔臂滑动配合。利用调节螺栓(3)通过均布在固定圈(4)上的螺孔将推进器压紧,使其对密封件(8)产生压力,在外套管(12)内腔的另一端为介质压力室(10),其内充满管道内的自身介质,该介质以相反方向,通过活动圈(9)给密封件一补偿压力。在上述两种压力的作用下,将密封件(8)压紧,从而实现密封。同时,靠活动圈(9)、弹性密封件(8),弹簧推进器一套装置,来补偿因冷热而使管道变形所引起的位移,使之始终处于密封状态。
由于该伸缩器的外套管内腔装有柔性连接的整体弹簧推进器,并利用该推进器及自身介质的压力,同时将密封件压紧、密封。所以它密封效果好。同时,它的体积小,重量轻,制造工艺简单,易装配,检修方便,造价低,并且容易保温。
